Should the amount of open trade threads be limited?

Its getting on my nerves how a lot of people bump around 3-6+ trading threads per hour trading the same exact items.
( like the guy trading Dark siders gift and made around 10 topics within a month )
I do know there is quite a big amount of big traders here, despite that i see most of them having 1 to 3 open threads trading different items, however, people who trade the same exact items and needlessly make new threads and bump them just to ask for different items which is filling the pages pretty quickly if u keep track of them ( did so this week ).
So how about limiting those a bit? i don't see the point why people make duplicate threads just to bump them all it once.
If bumps get limited to 2 threads per hour or so.
Or lets say having a new rule that limits them ( like don't make a new threads trading the same items for different stuff, only edit your old thread ).

note: keep in mind that the number of steam users is rapidly increasing per year. so the longer it takes the bigger the mess here

side note: there goes the blacklists from people doing it xD
